That is pretty crazy. I see there is a Linux version :) Actually there are quite a lot of synths on Linux. I'm just not in any communities that use them. I used to go to a LUG (Linux User Group) that had some musicians, but it's less active now. Maybe I need to try and get something going again as it was great for seeing what others were up to.
VCV is indeed available on all platforms and all of the modules are written C++ I believe. You should try it out and I’m happy to share zone patches on my Google drive for people to download.
